Toshinori Yagi, also known as All Might, is a pro hero that has super strength. He has two forms: One where he is normal, skinny, and sickly, and another where is is strong, heroic, and has lots of muscles. All Might is a very stoic and dependable figure, always inspiring others to do their best. He is the mentor to Midoriya, and is always encouraging him. While he knows that he has to be realistic sometimes, he often pushes himself past his limits.

All Might's voice should be in the low to very low range, and when in his muscle form, sound heroic and boisterous. However, in his sickly form, he sounds a little more shaky, and not nearly as energetic. The first line should be read in the heroic voice, the third line should be read in the shaky voice, and the second line is up for interpretation. All Might's English voice is Chris Sabat.
